RE: [Histonet] E.M. precipitate

"Bonner, Janet"

It could very well be formalin precipitate if the specimens had come into contact with formalin before being submitted in Gluteraldehyde solution.....or it could be lead from the staining. @:)

We are having problems with black precipitate on our E.M. photo's. Does any one mind sharing your procedure with me. It has been checked and it is not bacteria. We think it is lead?
